Abstract

A method of producing shag pile fabric by forming a series of yarn loops around a looper which is then positioned onto a backing sheet; securing the series of yarn loops to the backing sheet by first stitching them along their center; then cutting one of the row of loops so formed so that the looper with the other row of loops may be moved over to the cut loops and across the stitching; securing with a second line of stitching the other row of loops to the backing sheet; cutting such other row of loops, freeing the looper; and thereafter repeating these steps over the entire backing to form the shag pile fabric.

Fi g. z

PRODUCTION OF SHAG PILE This invention relates to the production of shag pile fabric, particularly coverings such, for instance as floor coverings, cushion covets, toy animals and the like. It is accomplished with yarn wound on a U-shaped wire looper and sewn with a sewing machine onto a fabric backing. The loops are then cut to make a shag pile.

There exists today instructions for making this type of shag pile, as evidenced by the cited art. However, none of such instructions include the operation of folding an uncut fringe or loop after a first stitching and then stitching again prior to cutting such uncut loop. Tools employed in these instructions have been made of cardboard, wood or a bent coat hanger. However, none are like the tool in this invention. Hereafter the tool will be referred to as a looper.

This invention results in rows of double stitched fringe comprising a series of U-shaped yarn sections being stitched first in their centers to a backing, secondly a slight distance to one side of the first stitching and over both sides of the U. The looper employed may be a bent wire with a plastic tube forming a U-shaped member. According to the invention, yarn is wound around the looper in order to form loops, whereupon the loops are secured to a backing by sewing down the center of the looper, thus forming a double fringe of loops. The lefthand loops are cut, the looper is moved to the left which folds the right loops over the left cut loops. The second stitching is sewn about inch to the left of the first stitching, over the folded right loops. These remaining loops are then cut. This frees the looper so that the next row can be started.

One object of this invention is to provide a way of making a firmly attached double-stitched shag pile that can be accomplished on a home sewing machine. A second object is to provide a looper per wherewith an entire row can be stitched with the loops remaining on the looper so the loops can be quickly and efficiently cut all at one time to form a shag pile. A third object is to make the step of the second stitching easily and quickly accomplished by means of the looper holding the fringe back instead of manually pushing the fringe back while the second stitching is being completed. A fourth object is to provide a rigid long-lasting looper that can be bent easily to different measured widths.

FIG. 1 shows a wire looper with four completed loops.

FIG. 2 shows four loops after the first stitching has been completed and the left loops have been cut.

FIG. 3 represents a backing partly provided with pile and the looper holding the right-hand loops over the cut left loopsthe right loops ready to be cut after the second stitching has been completed.

FIG. 4 shows a cross section of the end product of one complete loop of a single strand of yarn.

In practice, a nylon shag carpet yarn, wool, acrylic or other yarn is chosen suitable for the end use. In the interest of clearness the yarn is shown in the drawing as being a pair of spaced parallel lines (i.e., not crosshatched) in FIG. 3 and as a pair of crosshatched parallel lines in FIGS. 1, 2 and 4. The drawing is not necessarily in perfect scale, but drawn in the interest of clearness. The rows are explained as starting at the left of the backing and proceeding to the right. Sections of backing can be sewn together for as large a rug as desired. A looper long enough to accommodate 24 inches of loops is a convenient length for making rugs.

To begin with, the yarn is attached at the extreme upper left-hand corner of the backing A at point 1 in FIG. 1. The I machine stitching is done in reverse from 1 to the edge 2 over the first loop, then the winding operation for the yarn about or around the looper continued. The loose end 3 is part of the first loop; the fourth loop is completed at 4. Stitching B is continued forward from 2. Loops are wound a certain number of times for each square S marked on the backing A. FIGS. 1, 2 and 3 show a one-strand loop for each square for convenience and clearness. When the row is completed the left hand loops are cut as at 5 in FIG. 2, preferably with an electric scissor. This is done by placing the cutters of the scissors against the wire looper and moving the scissor along the length of the row.

The looper is moved to the left as shown in FIG. 3 and the second stitching C is completed. The remaining loops at 8 are then cut in the manner as the first loops were cut, freeing the looper. The nextrows can then be worked. For the production of patterned fabrics, winding may be commenced with one color, the yarn cut and another color started.

The preferred looper is made of a metal wire heavy enough to hold its shape without bending too easily, such as 56 inch stainless steel. The angles indicated in FIG. 3 at points 9, l0,

and 11 are made so that the looper can be bent wider or narrower by bending these angles, which produces longer or shorter pile.

Each complete loop produces four shag ends as shown in FIG. 4, and is stitched to the base or backing A, first at or along B, and second at or along C.

I claim:

1. In the production of shag pile fabric, the steps of forming a series of loops or yarn around a looper,

placing said looper with said series of yarn loops onto a backing,

forming a first line of stitching down the center of said series of loops to secure said loops to said backing and thereby forming left and right rows of loops,

cutting said left row of loops,

moving said looper with said right row of loops to the left over the first line of stitching toward said cut left loops, forming a second line of stitching immediately to the left of and generally parallel to said first line of stitching thereby securing said right row of loops to said left row of loops and said backing, king, cutting said right row of loops, and

repeating the above steps over the entire backing to form the shag pile fabric.

2. The method of claim 1 in which the stitching is a machine stitching.

3. The method of claim 1 in which the stitching is a handsewn stitching.

4. The method of claim 1 including the step of premarking the backing to provide a marking for the first line of stitching.

5. The method of claim 4 in which the stitching is a machine stitching.

6. The method of claim 4 in which the stitching is a handsewn stitching.

Claims (6)
